Only qualified and trained personnel shall perform overhaul.
WARNING:
Personnel must read and understand all warnings and cautions.
WARNING:
Tool must be maintained in a safe working condition at all times and examined on a daily basis for damage or
wear. Any repair must be done by qualified personnel trained on Gage Bilt procedures.
WARNING:
Disconnect tool from its power source before performing overhaul. Severe personal injury may occur if power
source is not disconnected.
WARNING:
Excessive contact with hydraulic oil and lubricants must be avoided (See safety data sheet documents for all
applicable materials).
WARNING:
When operating, repairing or overhauling tool, wear approved eye protection. Do not look in front of tool or
rear of tool when installing fastener.
WARNING:
Use only Gage Bilt hydraulic hoses and couplings, or equivalent, rated for 10,000 psi. (689.5 bar) working pressure.
WARNING:
Ensure air hose is securely connected to avoid possible hose whipping (Air Actuated Tools only).
WARNING:
Depress lever (704345) and disconnect from air, with the piston in the rear position, before overhaul. Severe personal
injury may occur if air hose is not disconnected.
head cylinder removed. Hydraulic oil will eject forcibly from handle assembly.
Note:
•
Dispose of hydraulic oil in accordance with manufacture safety datasheet.
•
All tool materials are recyclable except rubber o'rings, seals and wipers.
•
Use of SERVICE KIT (745020), which contains a complete set of o'rings, back-up rings, screws, washers and
gasket, can achieve a complete overhaul.
If a tool is performing poorly or leaking, a complete overhaul may be necessary.
Perform overhaul in a clean, well lit area using care not to scratch or nick any smooth surface that comes in contact with an o'ring.
Use of Lubriplate® #630-AA (Gage Bilt part no. 402723) or equivalent during reassembly to prevent tearing or distorting of o'rings.
1. Disconnect air supply.
2. Disconnect hydraulic coupler-male (585047) from power supply and air line (704311) from pump.
3. Remove hydraulic coupler-male (585047) from reducer bushing (403431) and drain hydraulic hose (A-317) into an approved
container.
4. Remove complete nose assembly and extensions (if applicable) from tool.
5. Remove four button head cap screws (402489) separating handle assembly (700344) from head cylinder (745366).
6. Replace o'ring (S832) and gasket (745124).
7. Remove end cap assembly (748118) and carefully push piston (745310) out of head cylinder (745366).
8. Using a small blunt object, remove back-up rings (401119) and o'ring (403815) from piston (745310) and o'ring (A-261) and
back-up ring (401092) from inside head cylinder (745366).
9. Reassembly sequence is opposite of disassembly. Be sure relative positions of o'rings and back-up rings are as shown in
exploded view and part list.
Coat hose fitting threads with a non-hardening Teflon® thread compound such as Slic-tite® (Gage Bilt part no. 403237). DO NOT USE
TEFLON TAPE.
1.
